Two different types of System Hooks can be used in yuuvis® Momentum, that support two different application types  types. Both of them react to function calls under a specified condition defined in SpEL, but their behavior after activation is completely different.

...

Any changes to the AMQP Hook configuration require a restart of the API Gateway service. More on AMQP Hooks can be found here.

...

Any changes to the Webhook configuration require a restart of the Servicesservices, that are responsable for the call of the affected functions. More on Webhooks can be found here.

...

The following example configures both a an AMQP Hook and a Webhook.

• The AMQP Hook applies to object imports and checks the contentStreams for the presence of a range attribute. Should the range attribute be detected, the AMQP Hook recognizes the imported content to be a compound document and initiates asynchronous text extraction of all the content parts.
• The example Webhook activates at every login and retrieves the roles of the user trying to authenticate  authorize (permissions)?.

To activate this configuration, both the API gateway and the Authentication service need to be restarted.
